XBA says: Mr. X Nightmare DLC is almost a must buy with how much long term gameplay it adds.
Half-Glass Gaming: "All in all, what you get with Mr. X Nightmare is more Streets of Rage 4, which is a good thing. The new characters are a lot of fun to play, and Survival mode is like avocado on a bacon cheeseburger, which is to say it’s deliciousness on top of deliciousness, and it makes a great game like Streets of Rage 4 even better."
Streets of Rage 4 was incredible. The one thing that was missing was more of it. Luckily, the developers noticed and brought us the Mr. X Nightmare.
You’ll know it worked when you start a game and notice that Roo now appears above the Streets of Rage 3 Shiva. You’ll have to input the code every time you start the game, but thankfully it’s not too complicated to do. Pretty cool, right? Roo is playable in all modes as well, however, Roo can’t pick up and use any weapons. And while that seems like a bummer, Roo has several powerful attacks and has the ability to roll dodge by pressing down or up twice in a roll. It’s pretty useful for getting out the way of attacks.
